Larry Page and Kitty Hawk

The Google founder is backing a Silicon Valley startup called Kitty Hawk, which has just revealed its first prototype.

The "all-electric vehicle" will fly over water and driver's won't need a pilot's license. It hopes to get it on sale to consumers by the end of the year.

Anyone wanting to sit back and relax won't want to go for this one - it's more like a flying motorbike than a car.

Lilium

The first glimpse of the Lilium jet is impressive. It's the first to nail the VTOL technology that lets it take off like a helicopter but fly like a plane. Read more about it here.

Aeromobil

​Another startup close to take off, Aeromobil showed off its latest design and started taking pre-orders for those dreaming of the skies. This car can drive on the road like any other cars but then takes of like a plane. Find out more.

Terrafugia

This firm has been working on flying cars since 2006.

It's already flown a prototype that has fold down wings to get it from sky to road, back in 2014.

But, it has ambitious plans for a much sleeker version it estimates will coe to market in 2025.

Ehang

​China's Ehang has shown off a drone-style pod that it hopes will be a taxi for the skies.
